The objective of the present Diploma Thesis is to analyze road accidents on Greek islands. This analysis will allow for the identification of tourism’s impact on road safety on the islands by correlating tourist arrivals with road crash and related fatalities. On that purpose, data on monthly arrivals, crashes, and fatalities were collected for 38 Greek islands, which were then divided into four groups based on their geographical location. Relevant charts were created for four representative islands to provide initial insights into the correlation between arrivals and accidents, as well as arrivals and fatalities in these areas. Subsequently, these correlations were further examined through the development of Generalized Linear Models and Random Forest models using the R programming language. The main finding from the analysis was that arrivals on an island are positively correlated with the number of accidents and fatalities recorded during that period. Additionally, while arrivals were correlated with accidents across each group of islands examined, the results differed, possibly due to better road conditions on islands with high arrival numbers but low accident rates.
